Canon Lens”L”生產年份編碼
The first letter, "U", indicates that the lens was made in Canon's Utsunomiya, Japan factory. Prior to 1986, this letter is moved to the last position of the date code.
U = Utsunomiya, Japan
F = Fukushima, Japan
O = Oita, Japan
The second letter, "R", is a year code that indicates the year of manufacture.
Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code.
Here is a table to make things simple:
A = 1986, 1960
B = 1987, 1961
C = 1988, 1962
D = 1989, 1963
E = 1990, 1964
F = 1991, 1965
G = 1992, 1966
H = 1993, 1967
I = 1994, 1968
J = 1995, 1969
K = 1996, 1970
L = 1997, 1972
M = 1998, 1973
N = 1999, 1974
O = 2000, 1975
P = 2001, 1976
Q = 2002, 1977
R = 2003, 1978
S = 2004, 1979
T = 2005, 1980
U = 2006, 1981
V = 2007, 1982
W = 2008, 1983
X = 2009, 1984
Y = 2010, 1985
